Capacitor technology made huge strides in the 1960s and 1970s - and has continued to advance even to this very day. Parts that were once the size of a Chicago bratwurst are reduced to the size of the baby gherkins that garnish them, with better specs across the board. And if you want to count the "supercaps" (you shouldn't), well, then everyone else might as well go home now.
Incidentally, what exactly differentiates a computer-grade cap from any other alum. electrolytic? @Eric If you're interested, I have somewhere a document from Mallory - I believe it may be a hardbound volume, perhaps a catalog - that describes the evolution of the multi-section aluminum can electrolytic, from the early versions up through the "EP" (Etched Plate) and finally "FP" (Fabricated Plate) designs. If you'd like to see it, I'll set it aside the next time I come across it.
